T 0 all whom it may concemt:

Be it known that I, RICHARD 'HUGHES OLIVER, a subject of thei King of Great Britain, and resident of the town offiBrlidg'eburg, in the county of Welland, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Brake'Beams, of which the following is a specification.

The invention relates to improvements in brake beams as described in the present specification and shown in the accompanying drawings that form a part of the same.

The mvention consists essentially of the novel features of construction whereby a brake beam is provided with a reversible strut. I

The objects of the invention are to provide a form of strut which may be used to equal advantage on either side of the car, thus eliminating the necessity of providing left and right hand struts, and generally to pro vide a beam'which will be inexpensive to manufacture, simple to adjust, efiicient in operation and durable.

In the drawings Figure 1 is a side elevation of a portion of a brake beam showing the strut in position.

Figure 2 is a longitudinal sectional view taken on the line A-A of Figure 1.

Figure 8 is a cross sectional view taken on the line BB of Figure 1.

Figure 1 is an end view of. Figure 1.

Figure 5 is a cross sectional view taken on the line C-C of Figure 2.

Like numerals of reference indicate cor responding parts in the various figures.

Referring to the drawings 1 is the brake beam to which is secured the brace 2 as customary in brake beam construction.

3 is a casting substantially cross shape in cross section and having an enlarged end portion 4 adapted to be secured to the beam 1 by suitable fasteners 5, the other end of said casting being in the form of a preferably circular disc 6 having openings therethrough for the reception of locking bolts 7 and being provided with an inwardly projecting key slot 8.

9 is a casting slotted at one end as at 10 to receive the brace 2 and being provided with a transversely arranged opening adapted to accommodate a pin 11 for locking said casting on said brace, said casting at its inner end being formed with an integral disc 12 similar to the disc 6 and located directly opposite said disc'6and having a key slot l3'therein.

14 is the strut, each-end of which is pro-' vided with a plate 15 of equal dimensions with the discs 6 and 12 being adapted to be rigidly secured therebetween by means of bolts 7, said strut being provided with a longitudinal slot 16 therethrough adapted to receive the brake lever 17 which is pivotally secured by means of a pin 18,said slot being cut at the proper angle to permit of said brake lever extending diagonally in rela tion to thebrake beam 1 and meeting the brake lever from the opposite side of the car.

The strut is preferably provided at each end with a projection or key 20 adapted to be inserted in the slots 8 and 13 respectively.

21 is a boss preferably formed integral with the casting 9 and having a suitable opening 22 therethrough for the reception of a chain or other member (not shown in the drawings) for securing sald casting to the car frame or other support, for the purpose of supporting said casting upon the removal of the strut.

' In the use of this invention it will be ap parent that the strut 14 may be used on either side of the car with equal facility by simply securing same between the castings 3 and 9 with the slot 16 extending in the position necessary to permit of the proper positioning of the back lever 17.

WVhat I claim is 2- 1. In a brake beam, in combination, a beam, a brace, -a head permanently secured to said beam, a head comprising a casting slotted at one end to receive said brace and adapted to be locked thereto by means of a pin extending across said slot, said heads being enlarged to form fiat faces oppositely faces being provided with bolt holes therethrough, and a strut having flat end surfaces adapted for engagement with said faces.

2. In a brake beam, in combination, a beam, a brace,'a head permanently secured to said beam, a head comprising a casting slotted to receive said brace, a pin extending transversely through said casting and across said slot for locking said head to said brace, each of said heads being provided with an enlarged inner endvpresenting a flat outer face, and astrut provided with enlarged end portions presenting fiat outer surfaces adapted for engagement with said faces, said enlarged portions being provided with openings for the reception of fastening members.

3. In a brake beam, in combination, a beam, a brace, a head permanently secured to said beam, a head comprising a casting slot ted to receive said brace, a pin extending transversely through said casting and across said slot for locking said head to said brace,

each of said heads being provided with an enlarged inner end presenting a fiat outer face, a strut provided With enlarged end portions presenting fiat outer surfaces adapted for engagement with said faces, said enlarged portions being provided with openings for the reception of fastening members, said strut being provided With projections from the ends thereof adapted to enter slots in the enlarged portions of said heads. and a pierced lug integral with the head carried by said brace.
